NHTSA Complaint #11445030 — 2019 SUBARU IMPREZA

When driving the vehicle the engine was not getting enough power and it was shifting oddly. I took it in and was told there was excessive carbon buildup on the heads, and there is not a good fix for the problem. Without having the engine torn apart this could of caused the car to not speed up properly or the engine to malfunction while driving the vehicle. This could have caused serious injuries to me or others on the road if the problem would not have been addressed. The vehicle was taken to the Subaru dealership, where the engine had to be taken apart and the heads had to be machined to get the carbon off. I was also told there was no preventative maintenance to avoid this problem. There were no warning lamps, lights, or other warnings to notify me of the problem other than the engine not having normal power when over 2000 RPM. It has also taken the dealership almost 3 months and counting to find and address the issue.
